An amplifier is the best way to ensure great sound quality. Good sound is much like going fast. The best way to achieve the goal is to add power. The Rockford Fosgate Punch Boosted Rail amplifiers pack a ton of power into a small space. Measuring 6.7"L x 4.2"W x 1"H, these amps crank out more than 300 watts of power and can be placed almost anywhere in your classic car. You can be sure that these amplifiers will deliver crisp, clear sound that you can hear even when cruising at high speeds with the windows down. When you purchase a Rockford Fosgate amplifier wiring kit along with the amp, you also extend the warranty of the amp for an extra year, giving you a 2 year warranty.
